Short text
Axially spilt case pump mounted on a base frame.
Tender text
Non-self-priming, single-stage in-line centrifugal pump with axially split housing and double-sided suction impeller for installation on a base frame. Sealing between the two parts of the pump housing is achieved by means of a paper gasket. Shaft sealing is ensured with a flushed mechanical seal or with a cooled stuffing box packing. The system is optionally delivered as a *Complete unit, comprising a pump with semi-elastic coupling, coupling guard and motor on a common base frame *Pump with semi-elastic coupling, coupling guard on a base frame *Bare shaft pump, without base frame Utilisation *Raw water intake, pressure boosting and general transport in power plants, waterworks and municipal drinking water supply networks *Cooling water and industrial water supply in power plants and industrial facilities *Irrigation in professional irrigation/agriculture *Pumping of heating water (in accordance with VDI 2035 Germany) and water-glycol mixtures Special features/Product advantages *Reliable continuous duty for an efficient drinking water supply over extensive piping networks – can be tailored to suit your exact requirements *Reduced energy costs through high overall efficiency *Simplified and shorter alignment process thanks to tolerant coupling (option) and motor adjusting device *Increased operational reliability thanks to quiet-running hydraulics with lower vibrations and reduced noise level *Reduced cavitation tendency through optimised NPSH performances  *Lower space requirements due to compact design *Also available as certified drinking water version – optionally with Ceram CT coating also approved for drinking water *Optionally available with Ceram CT coating – for an efficiency increase of up to 3 % *Maximum volume flow of up to 4500 m³/h
